In this paper. we consider a transmit power allocation problem for secure transmission in multi-hop decode-and-forward (DF) full-duplex relay (FDR) networks. where multiple FDRs are located at each hop and perform cooperative beamforming to null out the signal at multiple eavesdroppers. For a perfect self-interference cancellation (PSIC) case. https://foldlyers.shop/product-category/usb-3-1-type-c-gen-2-to-usb-type-c/
